I'm looking at getting a set of wheels that are
17x9 with a +25 offset.
Tires are 245/45/17

I have a 93 rx7 lowered on rsr springs.

I was wondering if anyone knows if these will fit with no problems. Don't really wanna have to roll/pull the fenders

 

Not a good fit. Too far out, notably too tall for the front.

 

Damn, what is a good offset?

 

For your best answer, check out sticky #3 at the top of this section. Searchs will also reveal a lot of discussions.

Also, staying close to stock diameters on tires will help, check out Tire Rack, among others, for sizing data on the tire sizes you are interested in.

For a quick answer, about 45mm +/-, depending...

 

Alright thanks. I'll check that out.

I have come across a few discussions while searching but they were for 18s

 

Check this thread for an old picture of my 17x9's:
